Lilac, with large inflorescence, luxuriant flowers, elegant and fragrant flowers, strong habits and easy cultivation, is widely used in gardens. Let's share the cultivation methods and precautions of lilac flower:
Cultivation method of beautiful lilac flower
1. Seed treatment: soak the seeds in hot water at 40 ~ 50 ℃ for 1 ~ 2 hours, then mix them with one part of seed and two parts of sand, place them in the sunny place, cover them with straw bags or sacks, and water them frequently to keep them moist. After about one week, the seeds can germinate and then sow.
2. Sowing time: can be in spring, autumn two seasons in indoor basin sowing or open field border sowing. In the north, spring sowing is the best.
3. Sowing method: the sowing method of Syringa oblongata is drilling, the depth of furrow is more than 1 ~ 2cm, and the distance between furrows is 10 ~ 15cm. 1000 grams of fully decomposed organic fertilizer and 100-150 grams of bone meal were applied to each hole, and they were fully mixed with soil as base fertilizer. Fill the ditch with enough bottom water, and then spread the treated seeds evenly in the ditch. Cover the soil with soil and cover the seeds. The depth of covering soil is suitable for no seeds. After the seedlings are excavated, the seedlings are intercalated according to the emergence situation. According to the principle of removing the weak and retaining the strong, the strong seedlings can be retained.
4. Planting: clove should be planted in the sunny place with loose soil and good drainage. Generally, it is planted bare root before sprouting branches in spring, and the plant spacing is - 3M. The diameter of 2-3-year-old seedlings should be 70-80 cm and 50-60 cm deep. 100 grams of fully decomposed organic fertilizer and 100-150 grams of bone meal were applied to each hole, and fully mixed with soil as base fertilizer. After planting, water shall be poured once every 10 days for 3-5 times continuously. After each watering, the soil should be loosened to keep moisture, so as to improve soil temperature and promote the rapid growth of new roots.
2、 Potted plants:
1. Choose basin: the directional bonsai should choose medium deep pottery basin, square basin or round basin. Basin color to light blue or light yellow is good, and purple, white flowers can contrast.
2. Pot planting method: the survival clove plant can be planted in the pot from February to March. When planting, trim the root system, leave more fibrous roots, so that the root system in the potted plant can be expanded, and the soil should be compacted to make the root and soil closely connected. The covering soil is 2 ~ 3 cm lower than the basin mouth, which can be poured through.
3、 Maintenance techniques of Syringa
1. Soil: Lilac has strong resistance to stress, and has no high requirement for soil. It is suitable for growing in fertile, loose and well drained soil, and it is difficult to grow in low-lying and wet places.
2. Watering: clove has strong adaptability and extensive nursing methods. At ordinary times, as long as attention is paid to weeding, waterlogging prevention in rainy season and watering in drought, it can grow smoothly.
3. Sunshine: cloves like plenty of sunshine, but also resistant to half shade, so we should pay attention to planting in places that can provide enough sunshine.
4. Temperature: clove like tropical island climate, climate characteristics of the original area belongs to the equatorial rainforest climate, the lowest monthly average temperature is 21 ℃, when the low temperature reaches 3 ℃, it can lead to plant death.
5. Fertilization: clove does not like big fertilizer, avoid excessive fertilization, so as not to cause branches to grow excessively and affect flowering. Generally, composting can be applied once every year or before winter.
6. Insect pests: clove diseases and insect pests are few. The main pests are aphids, bag moths and moths. It can be sprayed with 800-1000 times 40% dimethoate emulsion or 1000 times 25% imiphos emulsion.
7. Turning pots: Turning pots every 2-3 years, combining with turning pots, pruning roots, removing some old roots and over long roots, weeding out 1b2 old soil and replacing with new culture soil, so as to facilitate the development of root system, luxuriant leaves and flower propagation.
8. Pruning: before the clove sprouts in the middle of March, it is necessary to prune the clove, remove the over dense branches, thin and weak branches, disease and insect branches, and cut the vigorous and long branches in the middle to make the crown ventilate and light transparent. If there is no seed left after anthesis, the residual flower and the two buds at the lower part of the flower ear can be cut off to reduce the nutrient consumption and promote the germination of new branches and the formation of flower buds. After defoliation, one-time pruning can be carried out to keep the crown round and beautiful, which is conducive to the growth and flowering of the next year.
Tips for planting lilac in the park: 1. Windproof work should be done before the typhoon comes at young age. The trunk of clove plant can be fixed with rope and bamboo to reduce the shaking of clove plant caused by typhoon, so as to reduce the harm.
2. In July, September and October of each year, weeding is carried out around clove plants and the plants are covered with grass, but don't turn them up with hoes to damage fragrant roots. Weeds in other parts of the forest land are cut off to cover the ground, and can also be used as green manure to cover the ground instead of natural vegetation. Weeding shall be carried out until the crown is closed and the growth of weeds can be restrained.
3. After planting 3-4-year-old seedlings, strong pruning should be carried out near the ground branches after planting, that is to say, the trunk should be cut from 30 cm away from the ground. After cutting off, strong branches will grow quickly, making the crown full, and the next year will be able to produce luxuriant flowers.
